Description
Technical field
The present invention relates to a kind of overspeed testing apparatus, relate in particular to a kind of overspeed testing apparatus of elevator.
Background technology
The blower fan tower barrel elevator; be used for the equipment of manned or loading with other similar vertical lifts; in use for the purpose of safety; all need to dispose fall arrest and overspeed protection device; be used for protection when the unexpected disconnected rope of generation equipment; or stall can stop equipment by this device when surpassing the speed of safety.Must comprise speed detector in the wherein this fender guard, be used for the check implement running velocity and whether surpass safe limit value, trigger relevant stop mechanism action then.
Existing speed detector all is mechanical, what be that example usually adopts with tower tube elevator is safety lock, its principle of work is: by safety lock is fixed on the elevator, run through upper and lower fixedly steel cable in the tower tube, the steel wire penetrating safety lock, when elevator moves up and down, steel rope will slide in safety lock, drives one of them rotating centrifugal mechanism, if sliding velocity surpasses setting value, rotating centrifugal mechanism will be triggered, and reaches the purpose that tests the speed.
The problem of this technology is: structural adjustment is set to very difficulty of command speed; Owing to be machine up, for batch manufacturing quality stability control difficulty; Volume ratio is bigger; Need on the structure to cooperate the cost height with the outer wires rope; Total system structure design and install, safeguard all more complicated on the spot; Because the member of forming is many, relates to manufacturing, on-site installation, maintenance and adjust a plurality of links, so reliability reduces greatly; The elevator of friction speed needs the product of different size; This device precision is difficult to do height; In addition, this device is only to set a hypervelocity value, for adopting the application scenario of different hypervelocity setting values to use in different operating modes.
Summary of the invention
The technical issues that need to address of the present invention have provided a kind of electronic type overspeed testing apparatus, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions:
The present invention includes: power module; Also comprise: acceleration sensor chip, MCU chip (microprocessor), driving output module and control load module; Described power module links to each other with the module that MCU chip, driving output module, acceleration sensor chip and control load module constitute; Described MCU chip (microprocessor) links to each other respectively with driving output module, acceleration sensor chip and control load module.
Compared with prior art, the invention has the beneficial effects as follows: real machine debugging, easy to maintenance; The conveyor line circuit board manufacturing, software set parameter, batch manufacturing quality stability height; Volume is little; Simple in structure, cost is very low; Directly be fixed on optional position on the elevator, do not need other any additional matching mechanisms, easy for installation, the reliability height; For the elevator applications occasion of friction speed, only need to set different parameters and get final product, the product commonality is very good; Product velocity test precision is far above the existing mechanical device; Adopt different hypervelocities to be worth the application scenario for needs in different operating modes, only need to realize related request by the control signal of control input device.
Description of drawings
Fig. 1 is a module map of the present invention.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is described in further detail:
As seen from Figure 1: the present invention includes: power module 1; Also comprise: acceleration sensor chip 2, MCU chip (microprocessor) 3, driving output module 4 and control load module 5; Described power module links to each other with the module that MCU chip 3, driving output module 4, acceleration sensor chip 2 and control load module 5 constitute; Described MCU chip (microprocessor) 3 links to each other respectively with driving output module 4, acceleration sensor chip 2 and control load module 5.
What the acceleration sensor chip among the present invention, driving output module, MCU chip and control load module adopted is the prior art hardware module.
Relation between each module of the present invention is: power module 1 is used for providing electric power to installing each module work; Acceleration sensor chip 2 is used for the perception self-acceleration to be changed, export variable quantity to MCU chip 3, MCU chip 3 reads accekeration with appropriate frequency (being defined as f) and (is defined as a), whenever read an accekeration, just being multiplied by the time cycle (is defined as t, t=1/f), product adds up, and what obtain is exactly speed (being defined as v, v=∑ at); The hypervelocity setting value of speed that the MCU chip calculates and storage inside compares, and the controlling and driving output module 4 output control signals if judgement exceeds the speed limit trigger outside corresponding shutdown feature action; Control load module 5 is to be used to control MUC chip 3 mode of operations, also is used in addition the hypervelocity setting value of MCU storage inside is set or changed.
The concrete occupation mode of the present invention: be fixed on the elevator, when on the elevator during (or down) motion, the present invention just can detect the acceleration of motion value of elevator by acceleration pick-up, just can calculate the speed of elevator to detected integrated acceleration by the MCU chip, again the speed that calculates is compared with the hypervelocity setting value, just can judge very easily and whether exceed the speed limit, by driving output module output control signal, drive outside corresponding shutdown feature action when judging hypervelocity.
The present invention receives instructions such as elevator moves, stops by the control load module, knows the elevator mode of operation, thereby determines mode of operation, promptly determines to judge the condition of hypervelocity; The present invention simultaneously can set (or reading) MUC chip internal hypervelocity setting value and other controlled variable by control load module 5.
